  Version 1.0.1
  ChangeLog:
      1.0.1: changed the txtpath to use os.path module, ensuring that the path to
              text files is correct regardless of how the program is initiated.
      
  Calls an instance of printing_press.Editor and sends the articles to the Slack
  channel ID specified in the accompanying text file 'channel.txt'
  
  #### IMPORTANT ####
  This code requires you to have already registered a new Slack App, and added
  the bot user token to your system environment variables. See documentation at
  https://github.com/jtfarm/paperboy-academic for details.
